877 through inclusion of tc-hppa.h. Delete all forward declarations
878 for functions only used within tc-hppa.c, likewise for structures,
879 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
880 conditional code in a few small places.
882 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
883 structures, global variables, forward declarations together.

885 conditional code -- try to group conditional code together
886 into a few places. Make all functions and variables which
887 are only used within tc-hppa.c static. PARAMize all functions.
888 Add comments to functions. Delete unused functions, variables,
889 #defines, etc. Delete unused members within structures. Delete
890 ldil;ble hacks -- it is believed they were installed to work
891 around old gas bugs. Avoid using mixed case for local
892 functions, variables, and structures. Fix formatting problems
893 not found by GNU-indent. Add FIXME notices for things which
894 should be worked on the near future. Delete lots of old
895 useless (1.36 PA-SOM) code.

924 a multiple of the section alignment rather than always a
927 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

968 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
970 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
971 ELF, since the ELF object format does not have these type of
972 relocations. Change the abort into as as_bad and return
973 BFD_RELOC_NONE to silence compiler warnings.
974 (md_assemble): Keep track of the instruction size. Allow white
975 space between the $ and the constant for compatibility with older
976 gases and other assemblers.
977 (i386_operand): Skip spaces between $ and expression.
978 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

2038 * Extensive changes to permit symbols to contain any expression
2039 type and to delay the computation of the expression until the
2040 value is actually needed. This permits setting symbols to values
2041 calculated based on object code size. Expressions were changed to
2042 no longer be in a section, to stop the overloading of segment and
2043 expression type that previously occurred.
2045 * as.c (big_section, pass1_section, diff_section, absent_section):
2047 (expr_section): Added (used for dummy symbols which hold

2247 sy_resolved and sy_resolving single bit fields.
2248 * symbols.c (symbol_new): Don't initialize sy_forward field.

3365 avoid some redefinition complaints on some systems.
3366 (const, volatile): Don't need these conditionally defined if we
3367 use CONST and VOLATILE from ansidecl.h.
3368 (seg_name): Use CONST, not const.

3405 * Makefile.in (targ-cpu.o): Depend on config.h.
3407 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3409 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3410 dropping a space immediately following an identifier.
3411 * expr.c, write.c: Rewrote assert expressions to not use multiple
3412 lines; I don't think that can be done portably.
3413 * config/tc-mips.c (macro): Use $AT if target register is zero in
3414 load instruction, which it can be for a floating point load.
3416 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3437 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3439 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3440 to be on a single line.

3488 prototypes for all static functions. Moved existing minimal
3489 debugging format support info #ifndef OBJ_ECOFF blocks.

3540 * read.c (s_ignore): Don't declare is_end_of_line. It's
3541 redundant, and triggers a VMS gcc compiler bug.
3543 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3544 current segment as an argument. (Ignored in all cases but VMS.)
3545 All callers and definitions changed.

3841 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3842 md_relax_table): Use default zero initialization.
3843 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3844 latter, instead of selecting with preprocessor conditionals.
3846 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3848 * configure.in: recognise all sparclite variants
3850 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3856 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3858 * expr.c (operand): If character other than comma or newline is a
3859 logical end-of-line character, use the newline case.
3860 From Eric Youngdale:
3861 (operand): Set X_add_number field for floating-point numbers.
3862 (operand): Treat zero byte as end-of-operand.
3864 * configure.in (per-target): Look for with_bfd_assembler option.
3865 For now, only accept "no", until the merge is done.
3867 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3868 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3869 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3870 * read.c: Finish conversion to S_* macros in the VMS only
3871 parts of the program. Add "const" modifier to hex_value.
3872 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3874 * expr.c: Add "const" modifier to hex_value.
3875 * symbols.c: Finish conversion to S_* macros in the VMS only
3876 parts of the program. Add "const" modifier to
3877 md_[long,short]_jump_size. Remove declaration of const_flag
3878 (which will be declared in obj-vms.h).
3879 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3880 Fix arguments to VMS_write_object_file.
3881 * config-gas.com: New file. Script for VMS systems to set up the
3882 configuration to build gas for VMS, and create config.status.
3883 * make-gas.com: Redone to work with new scheme.
3884 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3886 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3887 will swap bytes if needed on a big endian system. Use throughout
3889 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3890 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3891 types of malformed stabs. Change parsing algorithm so that we are
3892 more certain of having all of the information that we need on hand.
3893 * obj-vms.c (final_forward_reference): New function, used to help
3894 resolve the data types of as many struct elements as possible
3895 when some part of the struct is not fully defined by the compiler.
3896 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3898 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3899 as symbols as well in the object file. Look for external functions
3900 that start with "__vt.", and turn them into variables, since the
3901 g++ compiler is incapable of doing this.
3902 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3904 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3905 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3906 have the name of the source file yet.
3907 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3909 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3911 * read.c (s_data): Always use "data_section", since it'll map to
3912 SEG_DATA or SEG_E1 if needed.
3913 (s_lcomm): Likewise with bss_section.
3914 (s_fill): Use memset, not bzero.
3916 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3937 (section_alignment): Declare only if not BFD_ASSEMBLER.
3938 (big_section, reg_section, pass1_section, diff_section,
3939 absent_section, text_section, data_section, bss_section): If
3940 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3941 mapping to segT enum values.
3942 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3943 if these are used or defined, if BFD_ASSEMBLER.
3944 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3945 subseg_new split into two functions.
3946 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3948 * as.h (volatile): Don't define if already defined.
3949 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3951 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3952 declare with format attribute for -Wformat checking.
3954 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3956 * app.c, config/tc-*.c: Don't include read.h, since it is already
3959 * These are based on patches from Minh Tran-le
3960 <mtranle@paris.intellicorp.com>.
3961 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3962 obj_format coffbfd and gas_target i386coff for target.
3963 (i[34]86-*-isc*): New host (uses sysv).
3964 * config/i386aix.mt: Removed (no longer used).
3965 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3967 (LDFLAGS): Added, defined as -shlib.
3968 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3969 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3970 (DOT_LABEL_PREFIX): Define.
3971 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3972 name rather than L0\001.
3973 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3975 * symbols.c, symbols.h (local_bss_counter): Removed.
3976 * write.c (write_object_file): bss no longer uses
3977 local_bss_counter. Pass correct data and bss size to
3978 VMS_write_object_file.

3984 (size_section): Restored sanity check.
3985 (do_relocs_for): Base section address on s_paddr rather than
3986 computing it. Adjust a29k R_IHIHALF special case to account for
3987 section paddr (used to require paddr to be zero). If there are no
3988 reclos, set s_relptr to 0. Set relocation size in object_headers.
3989 (fill_section): Always set s_vaddr here, removing
3990 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3991 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3992 Set STYP_INFO for .comment.

3996 H_{SET,GET}_* macros.
3997 (do_linenos_for): Set lineno size in object_headers.
3998 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3999 set s_vaddr here. If string_byte_count remains 4, set it back to
4000 0, and only write strings out if there are some. Call
4001 fill_section before do_relocs_for and do_linenos_for.
4002 (obj_coff_section): Handle optional quoted second argument giving
4003 section characteristics.
4004 (obj_coff_bss): Added to handle .bss.
4005 (obj_coff_ident): Added to handle .ident (puts string in .comment

4008 (fixup_mdeps): Change to segment. Call frag_wane after
4010 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4011 adjustment (already happened only for common symbols, but this is
4013 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

4025 (do_scrub_next_char): For \", return " not '.
4026 (symbol_chars): Now const.
4028 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4029 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4031 * config/obj-coff.h: Don't use #elif.
4033 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4034 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4060 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4061 using ZERO_BASED_SEGMENTS.
4062 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4063 never set segment address for SEG_E2 (.bss) and don't write out
4064 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4065 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4066 definitions, and don't merge tags with non-tags. Check for .bf
4067 rather than just checking whether the second character is b and
4068 the third character is f.
4069 (obj_coff_val): gcc can generate values which we don't handle
4070 correctly; discard information for now, since it only affects the
4071 debugging information.
4072 (tag_find_or_name): Don't insert tags in the symbol table.
4073 (yank_symbols): Don't merge labels.
4074 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4277 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4278 so widening works consistently.
4280 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4282 * version.c: Put conditional "const" before version_string, not

4285 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4286 printed rep of null character.
4288 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4290 * obj-coffbfd.c (write_object_file): check return value of
4293 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4295 * Support for i386-sysv.
4296 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4297 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4298 be used to set them all to zero as was done before.
4299 (fill_section): segment addresses now set in write_object_file.
4300 (fill_section): Don't set STYP_NOLOAD for .bss section.
4301 (fixup_segment): 386 uses strange common symbol format.
4302 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for

4334 * tc-z8k.c: lots of bug fixes
4336 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4338 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4339 #elif, since it is not supported by old compilers.
4340 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4341 couple of expressions in tc-m68k.c.
4343 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4345 * read.c (cons): If NO_RELOC is defined, use it.
4347 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4349 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4351 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4352 local labels to start with a .) and set REGISTER_PREFIX to %.
4353 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4371 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4372 sections starting from zero, rather than making them consecutive.
4373 This makes subsequent reloc calculations easier, esp if the object
4374 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4375 allocate lcomm in .data rather than in .bss. It seems that some
4376 tools can't cope with a non-zero sized bss before linkage.
4378 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4380 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4399 * Makefile.in (install): if $(tooldir) exists, install as in
4402 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4404 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4405 .word is < -32768 or > 32767. The -J flag causes the error to be
4406 ignored. This is to catch over-sized switches generated by gcc on
4407 systems which don't support the broken .word hack.
4408 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4409 write.c (fixup_segment): check for signed .word overflow if
4410 WARN_SIGNED_OVERFLOW_WORD.

4429 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4431 * input-scrub.c (input_scrub_push): call input_file_begin, not
4433 messages.c (as_perror): print ": " between the passed in error and
4434 the strerror, like perror does.
4436 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4439 From Steve Chamberlain:
4440 Makefile.in: Handle m68*-*-coff*.
4441 read.c, read.h: add mult argument to s_space
4443 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4444 Motorola and MIT syntax; gas can now assemble either type of
4446 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4453 (fixup_segment) set fx_subsy to 0.
4454 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4456 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4459 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4461 * Makefile.in (LIBS): Include opcode library.

4486 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4488 * config/tc-m68k.c (init_table): Now const. Always include 68851
4489 data, so that "bc" is available to 68040 cache instructions.
4490 Added "tt0", "tt1", and 68ec030 variants.
4491 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4492 (enum _register): Added TT0, TT1.
4493 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4494 line number correctly in "internal error" messages. Don't print
4495 architecture-mismatch message for operand errors.
4497 From Colin Smith (colin@wrs.com):
4498 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4499 than install_operand.

4520 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4521 has already been formatted (but may still contain %-characters).
4524 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4526 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4527 written with indirection on the last two operands, which can be
4528 either data or address registers. Added a new operand type 'r'
4529 which accepts either register type. Added '(' to notend stuff in
4530 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4549 their not having symbols associated.
4551 * tc-i960.c (norelax, instrument_branches): Default initializer is

4577 being used with args swapped, causing occasional lossage when
4578 refilling buffers after an include file.

4637 ancient or broken compilers.
4639 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4640 processor/opcode mismatch, so reword the error message.

4755 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4757 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4758 calc the base of relocs correctly.
4759 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4761 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4763 * as.c, write.c: use -K rather than -k for the broken word warning
4766 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

4774 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4776 * write.c (write_object_file): For b.out format, round up section
4777 start addresses to match required alignment.
4779 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4781 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4782 where gcc looks for it.
4784 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4786 * Makefile.in: Changed some lines to be less confusing for some
4789 * input-file.c: Conditionalize on _IOFBF, not VMS.
4791 * read.c, write.c: Change a series of ifdef/elif to
4792 ifdef/else/ifdef etc.
4794 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4796 * symbols.c (fb_label_init): fix sizeof to memset.
4798 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
4800 * Makefile.in: install the man page.
4802 * Makefile.in: pass down MAKEINFO explicitly on info.
4804 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
4806 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4808 * flonum-const.c: renamed flonum-konst.c to stop dos name
4811 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4813 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4814 tc-m68k.h to te-sun3.h.
4816 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4818 * configure.in: vxworks68 gets te-sun3.h.
4820 * expr.c: remove limitation that local_labels_dollar or
4821 local_labels_fb must be < 10.
4823 * symbols.c: remove local_labels_dollar, replace with a function
4824 interface for a sparse array. All users adjusted.
4826 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4828 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4830 * doc/Makefile.in: commented out line for building as-all.texinfo.
4833 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4835 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

4847 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4849 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4852 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4854 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4856 * expr.c (operand): if can't work out what sort of operand it is,
4857 then look through FLT_CHARS for a hint.
4859 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4861 * Makefile.in, configure.in: removed traces of namesubdir,
4862 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4863 copyrights to '92, changed some from Cygnus to FSF.
4865 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4866 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4867 copyrights to '92, changed some from Cygnus to FSF.
4869 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4871 * expr.c: If an expression is single comma, then return with
4872 SEG_ABSENT rather than an error - since the sparc front end does
4873 really strange things with things like fbge,a
4875 * as.h: include bfd.h if using many sections
4876 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4877 local labels didn't work.
4878 * listing.c (list_symbol_table): don't core dump when there's no
4880 * write.c, write.h: call fix_new with the right number of args on
4882 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4885 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4887 * app.c: MRI compatibility - allow single quote to start a string.
4888 * as.c: fix typo recently introduced.
4889 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4890 * expr.c: Much rewriting, to accomodate MRI syntax for
4891 expressions. Also easier to read now.
4892 * listing.c: Put back defuns
4893 * read.c: modified to accept MRI syntax, put back listing pseudo
4894 ops so that an assembler built with NO_LISTING ignores list ops
4896 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4897 machine is a SPARC or a 29K.
4898 * config/obj-aout.c: added s_sect pseudo op
4899 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4900 fill in the timestamp.
4901 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4902 anymore, define all the relocs which the tc-<x> bit will use so we
4903 can translate from them to the coff types.
4904 * config/tc-a29k.c: reloc_type isn't ane enum any more
4905 * config/tc-m68k.c: Added NO_RELOC definition.
4907 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4909 * Makefile.in: put header files before C source for TAGS; remove
4910 references to non-existent syscalls.h.
4912 * read.c, write.c subsegs.c: back out the .bss changes.
4914 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4916 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4920 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4922 * symbols.c (local_label_name): symbols now start with ^A.
4924 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4925 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4926 generate these sections. .align: will use NOP_OPCODE or 0
4927 for padding. This is just for being nice to the
4930 * expr.c (operand): changed to generate local label "\001L0"
4931 starting with a ^A so that it is recognized as a local label.
4933 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4935 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4936 i/o opcodes - inb, inw, outb and outw. string manipulation with
4937 att syntax - scmp, slod, smov, ssca, ssto.
4939 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4940 to just after .file .
4942 In obj_crawl_symbol_chain() where it tries to put the external
4943 symbols apart, with the condition:
4944 (!S_IS_DEFINED(symbolP) &&
4945 !S_IS_DEBUG(symbolP) &&
4946 !SF_GET_STATICS(symbolP))
4947 it was moving too many symbols out. So I switch it back to the
4949 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4951 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4952 so that we don't use the F_RELFLG which make the linker complain
4953 that somebody has stripped the relocation info.
4955 Also, the AIX ld program require that the relocation table
4956 is sorted by r_vaddr like the standard ATT assembler does.
4958 [he also changed the sizeof(struct ...)'s into the coff
4959 style FOOSZ macros. I'm not sure this is right, but I can't
4960 remember why. xoxorich.]
4962 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4964 * Makefile.in, configure.in, doc: use the doc. Build it, install
4967 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4969 * read.c: white space and comments only.
4971 * configure.in: use the new atof-ns32.c for ns32k.
4973 * write.c: comment change only.
4975 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4976 aren't yet integrated.
4978 * tc-i860.[hc]: blew off the dust. Something must still be done
4979 about conflicting relocation types.
4981 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4984 * tc-i960.c, tc-sparc.c: white space and comments only.
4986 * tc-a29k.h: delete duplicate macro definition.
4988 * new file atof-ns32k.c copied from hack's last unreleased gas.
4990 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4992 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4995 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4996 ChangeLog's prior to this are sketchy at best. I have logs.
4997 They just aren't ChangeLogs.
